Those are the only categories created to be 'publication' threads (i.e. read-only) vs. discussion threads - in other words articles not chit-chat. I you don't see anything nothing has been submitted yet.

If you would like to submit an article, please do so and once it's reviewed you will be added to the editorial group who can post in that thread.
